Hello there, I have a Wayne Kerr B424 LCR meter and am in need of a manual or some assistance. I bought the meter off ebay and it has no power cord, which really isnt a problem because it is UK powered and I'm in the US. It has a couple of plug ins in the back for DC power 12-20 volts with a 1 amp fuse. does this mean I can use a DC power supply with 12- 20 volts upto 1 amp? Thanks for any help.
